Y., a company of New York Application January 11, 1937, Serial'No. 119,967 In Germany January 17, 1936 5 Claims.

This invention relates to "spacebands used in matrix composing and line casting machines. The form of spaceband in general use comprises two mutually displaceable wedge-shaped members, the longer and thicker one having a dovetailed groove in which runs a dovetailed shaped guiding member fitted to the weaker portion which is provided with ears. The manufacture of the latter part offers difficulties, more especially as regards the machining of the dovetailed guide with the required accuracy. Heretofore it has been customary to make this part with the dovetailed guide in one piece, but in order to overcome the difficulties which arise in the machining thereof, it has been proposed to form the dovetailed guide in a separate part and to attach this part to the stationary spaceband wedge member by riveting or spot-welding. This procedure, however, gives rise to other disadvantages, more especially attributable to the number of rivets, or to the large number of spot-weldings needed, which cause the part to warp and make subsequent rectification extremely diificult.

The present invention is intended to overcome this disadvantage and with this end in view consists in a spaceband for a matrix composing and line casting machine comprising relatively movable members, wherein one of said members is formed of parts secured together by interengagement of portions thereof suitably shaped for the purpose. In one convenient embodiment of the invention the stationary part of the spaceband may be made in two parts joined together (without tension being applied) by projecting lugs or the like of one part, which engage with corresponding lugs or abutments of the other part, the two parts being joined together by means of a pin, rivet or the like.

The invention will be clearly understood from the following description of one constructional form thereof, shown by way of example herein and illustrated in the accompanying drawing, wherein:

Figure 1 represents a view of an assembled spaceband according to the invention;

Figure 2 represents a section taken on the line II-II of Figure 1;

Figure 3 represents a section taken on the line IIIIII of Figure 1;

Figure 4 represents the stationary part of the spaceband shownin Figure 1, without its dovetailed guide;

Figure 5 represents a section taken on the line VV of Figure 4;

Figure 6 represents a view of the part carrying the dovetailed guide, and

Figure 7 represents a view from above on Figure 6.

In carrying the invention into effect in one 5 convenient manner, and referring to Figures 1 and 4 to '7 (wherein the spaceband is drawn to the scale of twice full size) and Figures 2 and 3 (drawn to double the scale of the parts shown in Figure 1) the spaceband comprises the usual 10 long movable part a which is wedge-shaped and carries on one side a central dovetailed longitudinal groove. The rear wall of the groove is apertured as shown, in known manner. The two side stays which carry the dovetailed groove on their 15 facing edges are joined together by the connecting member (1 According to the invention, the stationary member is made in two parts, and consists of the wedge-shaped member proper 11 carrying the usual ears 0 adapted to guide the spaceband during its travel in the machine. The dovetailed guiding member is constructed as shown by the part (1, which consists of a narrow strip of metal, bevelled, as shown in Figures 6 and 7, along its 2 longitudinal edges. This part d is provided with two transverse members e, which are wider than the part cl, the ends of which are likewise bevelled in a sense opposite to that of the bevel of the part 01. The part at is also provided with an aperture J. The part b has two rectangular apertures g, 9 separated from each other by a transverse running stay h, having slightly more than twice the height of the members e on the part (1. On the edges of the apertures g and g are provided bevelled abutment members i, and an aperture 70 is provided in the stay h.

When assembling the members the part d is placed against the rear of the part b as shown in Figure 4, in such manner that the transverse strips e enter the upper open portions of the apertures g and 9 The part d is then slid downwardly, and the outer bevelled ends of the strips e are thus able to engage with the bevelled lugs i on the member 17, so as to secure the said parts together. In this position, the apertures f and k are in register and by passing a pin or rivet through these two apertures, relative movement of the two parts is prevented. The finished stationary part of the spaceband is then slipped into the dovetailed guide of the movable part a in the usual manner and is locked up.

It should be understood that various modifications of the form of the invention described above may be introduced without departing from the scope of the invention. For instance, in place of the bevelled lugs on the strips e and the bevelled lugs i, abutment surfaces of difierent shapes may be employed while in place of the two connections through the strips e and the openings y, 9 a single opening, correspondingly wider, or more than two openings, may be provided.

Having described my invention, I declare that what I claim and desire to secure by Letters Patent is:-

1. A spaceband for a matrix composing and line casting machine comprising relatively movable members, wherein one of said members is provided with a part securedthereto by interengagement of portions thereof suitably shaped to permit such inter-engagement by a relative movement of the member and part in their own plane.

2. A spaceband for a matrix composing and line casting machine comprising relatively movable members, one of which is provided with a part having lugs adapted for inter-engagement with the member when said part and member are moved longitudinally relatively to one another.

3. A spaceband according to claim 2, wherein said part and member are secured together by a rivet after mutual engagement of said lugs.

4. In a spaceband for, a matrix composing and line casting machine, a supporting member having two apertures centrally therein separated by a cross-bar, bevelled 'abutments extending longitudinally along part of each of opposite edges of each aperture, a plate with bevelled edges, and ofiset lugs, bevelled in an opposite sense, extending beyond the edges of said plate, said lugs being slid behind said abutments and. a

' rivet being inserted in said plate and'said cross bar, to secure said plate to the supporting memher as part thereof.

5. A spaceband for a matrix composing and line casting machine comprising relatively movable members, wherein one of said members is provided with a separate part having portions formed for inter-engagement with the member by a relative movement of the part and member in their own plane to secure'them together, and said part being formed with portions cooperable with the other member for sliding engagement therewith and being adapted to hold the members against facewise movement.
